To all whomt't ma concern Be itknown t at I, ARCHIE G. MAULE, a citizen of the United States, residing at South St. Paul,inthe county of Dakota and State of Minnesota, have invented new. and useful Improvements in Automatic Hose- Cou lers, of which the .following is a speck fication. v

My invention relates to improvements in hose couplings for railway cars and its obtoprovide simple and durable means adapted to automatically couple and 1 uncouple abutting hose sections beneath: the cars of a train. y

.A further object is to provide a device of this class adapted tosecurely seal the joint between hose sections as the same are i brought together.

' tremit B the hanger and C coupling comprises two My improved One section 18 identical coupler sections.

The hanger B consists of an anchor plate 10, a air of vertically depending arms 11 on said plate, braces 12 extending fromsaid arms to the plate, and a bracket 13 attached to said arms, said bracket :being formed at its extremity with a curved and upwardly inclined ide 14.3 The boa A is tiltable vertically and slid able longitudinally on the hanger B. Ribs 15, formed on'the central portion of "said bod ,are slidabl'e in the blocks 16,.each of sai blocks being provided with a stub bearing 17 mounted in the slot 180i an arm 11.

wardly andis formed with cars 19 at its ex- The block 20, pivoted at its ends in sai cars 19, is perforated to be supported by the guide 14. The spring 21, coiled about the guide 14, bears at one end against the block 20 and at its other end against the stop 22 on said guide and acts to yieldingly hold the body A in normal position with said block abuttingagainst the shoulder 23 of the bracket 13,.as illustrated in Fig. 1 of the drawin s. r

The couplin hea C is formed on the forward end 0 the body A and is shown in detail in Fig.4. The air pipe 24 passes from the center of the face of said head to a point below the body where it may be conveniently attached to an ordinary flexible hose. This pipe is formed with an enlargement 25 adapted to rest in a socket within the head 0, said enlargement being designed to prevent the'pipe 2 1 from moving rearwardlyin said head. The gasket 26, surroundin the end of said pi e, is seated in the hea C and extends shg itl beyond its face. I have pivoted the dog 2 within one side of said head. This dog is formed at its upper end with a stop 28 and its other end extendsdownward, said end being adapted to rest flush with theface of the head C and with v its extremity rotruding slightly beneath said head. T e bell-shaped guide 29 is formed on the head C at the side opposite the dog '27. Said uide is grooved at 30 to receive the dog 0? a companion coupling section and is supplied with a catch 31 to engage and retain said dog. The rod 32 is provided to engage the stop 28 on the dog 27 and lock the same'in position as illustrated in heavy lines in Fig. 1. This rod is slidably mounted in the head G, the block 16 and the bearing 33, the latter being on the body A. Said rod 32 is supplied with a lug 34 adapted to engage said block 16 and also with a spring 35 arranged between said lug and the bearing 33 to normally and yieldingly hold said rod in engagement withthe stop 28 of the dog 27. In applying my improved couplings to cars, one section (as illustrated in Fig. 1) is attached by any suitable means to each draw bar of the cars. These sections are airranged in identical positions with thecoupling beads C extending beyond the ends of the draw bars and withthe' faces of said heads slightly tilted so that in coupling, the

lower edges of said faces will first impinge against each other.

In operation the coupling and uncoupling of the sections is automatic. When the secguides 29 of the abuttingsections receive opposite sides of the heads C and direct the same into alinement with the openings of the pipes 24 and'the gaskets 26. The dogs 27 engage the faces of the opposite heads and are moved to upright positions as said heads meet. The stops 28 at the upper ends of the dogs 27 are engaged and locked by their respective rods 32 and the lower ends of said dogs rest in the grooves 30 of the guides 29 and are engaged by the catches ,31 which look said sect-ions together at the bases of their heads. Further movement of the cars toward each other forces the bodies A rearwardly on their hangers and moves them against the action of the springs 21. During this operation the bodies A are ilted by the guides 14 j and this tilting movement brings the faces of the coupling heads together from bottom to top, thereby forcing the abutting gaskets together and forming a tight joint between the air pipes 24. Rearward movement of the bodies A upon their respective hangers B is arrested by contact of the draw bars of the cars. Compensation for vertical play between the cars is provided in the slotted connection between the body A and hanger B.

In uncoupling, the draw bars are disconnected and as the cars recede from each other the bodies A are forced back toward their normal positions by t-hesprings 21 on the slides 14. During this movement the lugs 34 on the rods'32 engage their respective blocks 16 and withdraw said rods against the action of their springs 35, from -engagement with the stops 31 on the dogs 27, thus freeing said dogs and permitting the separation of the heads as they reach normal positions on their hangers. As said heads are separated, the lower ends of the dogs 27 are carried by the catches 31 back to normal positions. I have pivoted these catches '31 in the guides 29 so that the former will yield to receive the dogs 27 and thereby prevent damage to said dogs and catches, in case the dogs are inadvertently moved to locked positions before the sections are coupled.

What I claim as new and desire topro-- tect by Letters Patent, is:
